Fuel Consumption (merged topic)

[masda74]

350-400km per tank? Far out guys you do have a lead foot. I am getting between 500-600km a tank. Average fuel consumption is 12.6l/100km for city driving for me. Every so often I do give her a boot full to enjoy the drive home... keep in mind no freeway driving recently.

Even though I drive a BA I thought I'd just throw my figures up cos they don't seem right.

Around town I get 12-13L with an average speed of 50km/h but only get 350km if I'm lucky.

Freeway full tank with no stops I can get as low as 7L with an average speed of 100-110 and I'll usually get 500-550km.

Pretty average consumption if you ask me. I put it down to the old 4spd.

You mustn't be emptying your tank either. 7L/100 X 550km = 38.5 litres which is only just over half your tank. Same with 13L/100 X 350km = 45.5 litres.

With 7L/100 and a 60L fuel tank you should see 860Kms

Are you sure you are looking at av fuel no instant fuel dip into 7s on a slight downhill straight?

Yea some of these figures are pretty bad, I get 650-750km per tank towing my jetski on the open road. Is a 75litre tank being a ute of course.

100% looking at the average. It's mainly after I got my tune that the figures dropped. I'm pretty sure my fuel gauge works fine so the only thing I can think of is the ecu doesn't calculate it correctly somewhere along the line.

LOL all these guestimations.. what a load of crap. If you guys want to start throwing figures around why don't you back them up with some factual numbers.

Are ECU averages and other data based on the flow of the factory injectors if so does having bigger injectors fitted cause data to be incorrect?. Mine is out considerable since I had the tune with 60lb injectors. Trip computer average fuel consistantly 2-3 L/100km lower than actual usage calculated from fill up litres to km travelled

Anyone know if there is a way to correct this?

[Paulie2256]

Actually good question. How does the pcm get the instant fuel usage. Is it from fuel pressure or some sort of injector pulse calculation?

Would also like to know this as it seems like a similar problem to me.
